I'm working on a game arcade thing as a hobby project, themed around lockstep networking.

There's a website for this here: https://locksteparcade.com/

It's still very much a work in progress, with just two games. One is a version of the classic game "Lemmings". The other is a very minimal asteroids style inertial ship duel.

The games both use deterministic execution in lockstep across network participants, and provide interactive gameplay and smooth execution even if situations with up to quarter or half second lag times, and the methods used for this are then perhaps one interesting aspect of the project.

In each game, the local player sees their own controlled entities at current positions, and other player entities at historical positions.

In the lemmings game, the complication is that lemmings depend on their own world changes (e.g. they need to stand on a bridge piece they just built). So there is a kind of fork and merge mechanism that enables local and remote world changes to be eventually consistent.

In the inertial duel game, homing missiles have a deploy phase in which they transition between different update time frames, with exactly the same sequence of updates applied on each machine, but with these updates accelerated or slowed down to achieve the time frame synchronisation.

There is an offline part with a tutorial to go through for the lemmings clone, which gives a flavour of the thing. The networking part uses a dedicated server and is currently invite only, but if anyone is interested in trying this then please shout and I can send out server credentials..


Recent discussions about artificial intelligence safety have focused heavily on ensuring AI systems remain under human control. While this goal seems laudable on its surface, we should carefully examine whether some proposed safety measures could paradoxically enable rather than prevent dangerous concentrations of power.


The text you get when you click share should indicate which puzzle you solved, in some way (e.g. like the number in "Wordle 247 3/6").

Having some kind of graphic in this sharing text would feel nicer, I think, as well, somehow. (Could be just sequences of green blocks for each word, basically just showing how long the words you made are.)


Yeah thats a good idea thanks. It will help deal with timezones as well as the letters change at midnight your time.

Will have a think of the graphic I could add to sharing!


Right, this seems like an interesting subject, but not a lot of information there. Can anyone suggest better sources?

Any comments on the following: https://news.ycombinator.com/item?id=22662071



The concept of diminishing returns, perhaps, together with the corollary, by which I mean the fact that you can often get easier profits or make progress a lot more easily by switching to some less explored avenue.


Does this apply to PhDs?


When considering selling points, everyone seems to be focusing on the advantages of being able to run traditional games without console hardware or delays for installation, but no-one seems to be talking about how something like this could fundamentally change the constraints on multiplayer game design. I wonder what the server side looks like, and whether anyone is working on MMO type products that are designed specifically for this setup..


How do you think the unthinkable?

..

With a great big itheberg.


I don't know exactly how that bug bounty program works, but it feels like there may be some fundamental issues with bug bounties in the context of open source projects.

For example, what is there to prevent someone from introducing a bug into an open source project, first of all, and then subsequently claiming a bounty for identifying and/fixing it?

(Maybe this can end up by forcing more careful pull request auditing for security critical projects, but that seems like a big ask..)


As other posters have said, it seems like it can be tricky to incentivise cattle owners to add algae to their feed, check this has actually been added, in proportions that have the desired effect, and so on.

But how about if governments provide subsidised feed centrally, instead, with the algae added?


What if it turns out to make healthier cows? I'm not just making that up, I think it will probably have a positive effect - cows need iodine too! Not sure if it's enough to sway farmers.


This particular iodine compound is effective precisely because it kills methanogenic gut bacteria. Given that those bacteria are a normal part of cows' gut flora, it's reasonable to worry that killing them might be bad for the cows, and would be surprising if it was good for them.

Although, of course, it might be! That's why the only way forward is to test it empirically.


Can't believe this comment is the only mention of iodine in both the thread and the article. I supplement iodine daily and it's honestly changed my life.


Which supplement you are taking and where are you buying it ?


Get some blood work done before adding supplements to your diet. Creating an imbalance is even worst.


Ditto. Iodine and Magnesium have eliminated my asthma and had other positive effects - no sugar crashes two hours after eating for example.


Or just legislate that feed manufacturers must add the algae?


Sadly, I fear legislators won't do that until there's an economic advantage for their supporters. So they need some magnates to be convinced, and buy up the production before they go ahead.

Why would legislators make regulations that just save the planet but don't make them rich? /s


There couldn't possibly be any unintended side effects of that...


There are ways to mitigate unintended side effects. Start with a small small number of farms, AB test with no seaweed, small amounts of seaweed, medium amounts of seaweed, large amounts of seaweed, also AB test on which Farmers know which sample they are getting, iterate next year on results with larger number of Farmers. Buy insurance to compensate Farmers if the seaweed kills them. Discover why they died. Iterate with solution (if possible) or cancel (if seaweed always results in eventual death). Continue to keep large population of seaweed free cattle to mitigate possibly of extinction via unexpected long term consequences of seaweed.


Agriculture is already heavily regulated and inspected in terms of such things at least in the EU, owing to the fact that farmers get most of their income from subsidies and these are predicated on various terms.

Of course, it would be much simpler to just stop the nonsensical subsidies of environmentally and ethically disastrous ag products like beef...


> owing to the fact that farmers get most of their income from subsidies

Where on earth do people get these beliefs?


Depends on how you count, and if "income" is "revenue" or "profit".

~$200B/yr in subsidies in USA: https://en.wikipedia.org/wiki/United_States_farm_bill

$990B/yr food GDP in USA: https://www.ers.usda.gov/data-products/ag-and-food-statistic...


In my country it's 50+ %. While the EU paid direct cash subsidies are high, they only scrape the surface making up about 25% of the subsidies.

On top of the EU sibsidies there are direct national subsisidies and a wide spectrum of indirect national and EU level subsidies like export, pension, environmental, protectionist import duties, etc. And yes, beef production gets a similar share of subsidies as other types of farming.

I can't find good europe wide stats. I may have overgeneralized and the average may be under 50%. But the subsidies are still very high.
